Lisa Randall is to the Universe as Columbus was to Exploration

Lisa Randall talks about multiple dimensions of space. The 3 dimensions we know for sure about are: left, right, forward, backward, up and down and another is time. To me i find it incomprehensible to think about how there could be more dimensions but we do not even know what they possibly would consist of. She says that we cant picture another dimension. A two dimension world or a person living in the flatland would not be able to picture a three dimensional world and the same is true for us picturing a fourth or fifth dimension. I think that trying to discover more dimensions is a very interesting study. Its kind of like an explorer a couple centuries ago searching for new land. They had an idea that there was something more and slowly explorers began to trickle out to find this new place. Searching for another dimension is alot alike being an explorer. These physicists wonder what could be out in space and if there is possibly another dimension. Many people think what they are doing is crazy, but so did all the people who thought the world was flat and that ships would fall off the end of the world. CHAKS TAKE
